the proper and quantitative recognition of the scale of turbulence in regard to issues such as sediment transport is of major importance. different experimental techniques can be used to determining the scale of turbulence, but the accuracy of these techniques is open to question. in this paper, after a review of the taylor method, the restrictions and advantages of velocity measurement techniq...

This paper describes features in the structure of a laminar vortex ring ejected vertically from an elevated pipe into a uniform horizontal cross flow. Measurements are obtained by particleimage velocimetry (PIV) and flow-visualisation images are obtained by planar-laser-induced fluorescence (PLIF). Cross flow produces a shear layer over the open end of the elevated pipe. As a vortex ring is eje...

The introduction of Doppler velocimetry to obstetrics offered a noninvasive and safe imaging modality of indirectly assessing the fetal and uteroplacental circulation. Obstetric Doppler ultrasound plays an important role in detecting Intra Uterine Growth Restriction (IUGR). The early diagnosis of IUGR with the help of abnormal flow patterns in umbilical, uterine and middle cerebral arteries usi...

Introduction: The incidence of intrauterine growth restriction is approximately 10%. The management depends upon diagnosis, follow up and timely delivery of the fetus. Material & Methods: Prospective cohort study was conducted at a zonal hospital from Oct 2014 to Aug 2016 on 60 women with clinical suspicion of FGR. After confirming FGR with ultrasound, these patients were followed with umbilica...

Background. The transient effects of epidural bupivacaine 0.25–0.5% on the Doppler velocimetry of umbilical and uterine arteries had been reported, but the effects of continuous lower dose epidural bupivacaine (0.05–0.1%) infusion for labour analgesia have never been reported. In this study, we evaluated the effects of continuous epidural bupivacaine 0.075% on the Doppler velocimetry of uterine...

OBJECTIVES To reanalyze randomized controlled trials on the use of umbilical artery Doppler velocimetry in high-risk pregnancies and determine which high-risk pregnancies benefit from the use of Doppler velocimetry. METHODS Searching Medline, the Cochrane Library and Embase we found 13 randomized controlled trials on the use of Doppler velocimetry in high-risk pregnancies. Of these, six inclu...
